This work gives the method of transient time determination of the belt conveyor in the case of its start up in the example of a belt conveyor for ore at the open pit “Veliki Krivelj” with capacity of 2000 t/h. The analysis was made by calculation procedure and it represents a universal calculation method of conveyor belts whose results are indispensable for verification the reliable operation of selected electric motors during the start up of belt conveyor. Also, technical characteristics of all components of drive units are given as well as their layout.

This paperwork gives an analysis of reversal motion of the belt conveyor in the case of its stoppage in the example of a belt conveyor for ore at the open pit 'Veliki Krivelj', with capacity of 2000 t/h with inclination in material transport direction. The analysis was made by the calculation procedure using the 'contour bypass' method, which is a universal calculation method for conveyor belt calculation, whose results are indispensable for the selection of backstopping device of belt conveyor. Also, the principal of operation and technical characteristics the selected backstopping device are stated.
